When the Windows thread scheduler migrates these critical execution threads to E-core clusters or throttles the CPU Ring Bus frequency during dynamic load shifts, your frame-time stability collapses, causing visible hitching during gameplay.\u003c\/p\u003e\n\u003cp\u003e​Generic performance guides only tell you to lower in-game settings or apply basic power profiles.
